CHC @ ATL
Home plate: Tyler Jones
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Tyler Jones called the 140 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 132 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1+0.28▼6 · 1-2 strike called ball
Austin Riley vs Ryan Rolison - 2-0.13▼8 · 1-1 ball called strike
Ha-Seong Kim vs Trent Thornton - 3-0.13▼3 · 1-0 ball called strike
Ha-Seong Kim vs Colin Rea
Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
ABS — the Automated Ball-Strike System
5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Moisés Ballesteros — ump said ball, robot ruled ball: upheld.
- 2Drake Baldwin — ump said ball, robot ruled strike: overturned.
- 3Alex Bregman — ump said strike, robot ruled strike: upheld.
- 4Drake Baldwin — ump said ball, robot ruled strike: overturned.
- 5Matt Olson — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
